  • (a) transmitting, by an Online Certificate Status Protocol (OCSP) responder of an intermediary device between a plurality of clients and one or more servers, an OCSP request to a OCSP server for a status of a client certificate responsive to receiving the client certificate from a client during a Secure Socket Layer (SSL) handshake;

    (b) continuing, by the intermediary device, to perform remaining portions of the SSL handshake while the OCSP request to the OCSP server is outstanding;

    (c) establishing, by the intermediary device, an SSL connection for the SSL handshake; and

    (d) determining, by the intermediary, whether to terminate or maintain the established SSL connection based on the status of the client certificate received via a response from the OCSP server.
